FDA Approves First MRI-Guided Focused Ultrasound Device to Treat Essential Tremor

The U.S. Food and Drug Administration today approved the first focused ultrasound device to treat essential tremor in patients who have not responded to medication. ExAblate Neuro uses magnetic resonance (MR) images taken during the procedure to deliver focused ultrasound to destroy brain tissue in a tiny area thought to be responsible for causing tremors. 676 more words
